MOTUL AUTO COOL OPTIMAL -37°C is a ready to use coolant, based on monoethyleneglycol, with organic additives (OAT – Organic Acid Technology).

• Optimal protection of cooling systems against freezing and metallic parts against corrosion.
• OAT coolant technology provides an excellent thermal exchange and therefore improves engine cooling efficiency and prevents from boiling.
• This organic technology provides anti-corrosion properties that remain at high temperature and aging.
• Low corrosion inhibitors allow for extended drain intervals.
• Seals, hoses, pipes and plastic parts friendly.
• Nitrite free, amine free, phosphate free, borate free, silicate free.

Not just Meeting but Exceeding Standards for optimised Performance
The Motul coolant line exceeds many approvals and requirements to ensure excellent heat transfer for optimum operation of the engine or the hybrid system.

Different Formulations for different Applications
Different formulations allow the application for conventional vehicles, historic vehicles, hybrid vehicles, OAT requirements as well as for different machine types and a wider range of equipment.

Recommended Actions
Ready to use, do not add any water. Drain intervals: Refer to the manufacturers' recommendation. Do not mix with non-organic products. This product should not be used to protect drinking water systems against freezing. Attention, control or drain the coolant only when the engine is cold. Dangerous. Respect the use and handling recommendations.

Standards
ASTM STANDARD D3306 / D4985 / D6210, BRB BR 637, BRITISH STANDARD BS 6580, FVV STANDARD GERMANY...
